PRINCIPLES OF SOIL MECHANICS INVOLVED IN THE DESIGN OF RETAINING WALLS AND BRIDGE ABUTMENTS

IN A LARGE NUMBER OF EARTH PRESSURE AND FOUNDATION PROBLEMS THE STRESSES FOUND BY THE METHOD BASED ON ELASTICITY ARE INDEPENDENT OF ELASTIC CONSTANTS AND ARE CLASSIFIED AS PROBLEM OF PLANE STRAIN OR PLANE DEFORMATION. THESE ARE PROBLEMS INVOLVING TWO DIMENSIONS, AND IN THEIR SOLUTION AN ANALYSIS IS MADE OF THE STRESSES IN A VERTICAL CROSS SECTION OF THE EARTH EMBANKMENT OR SUPPORTING SOIL UNDER A FOUNDATION. THE LIMITATIONS OF THE ANALYTICAL METHOD BASED ON THE ASSUMPTION OF THE CONDITIONS OF PLANE STRAIN ARE INDICATED IN THE CASE OF THE SUPPORTING SOIL UNDER ABUTMENTS, PIERS, AND RETAINING WALLS. THE PRINCIPLE OF SUPER-IMPOSITION OF DIFFERENT SYSTEMS OF LOADING IS APPLIED TO PROBLEMS OF PLANE STRAIN IN DERIVING EXPRESSIONS FOR THE GREATEST SHEARING STRESS IN THE UNDERSOIL BELOW A SYMMETRICAL FILL AND A BRIDGE ABUTMENT. THE ACTIVE AND PASSIVE EARTH PRESSURES AND THE EARTH PRESSURE AT REST, IN THE EARTH BACK OF RETAINING WALLS, ARE EASILY DETERMINED BY USING THE ANALYTICAL METHOD OF COULOMB AND THE GRAPHICAL METHOD OF MOHR. THE CONDITIONS OF PLANE STRAIN ARE ASSUMED IN THE APPLICATION OF BOTH METHODS. /AUTHOR/
